To all 'whom it may concern.'

Be it known that I, WILLIAM I-I. MCAN- DREWS, a citizen of the UnitedStates of America, and resident of Chicago, Cook county, Illinois, haveinvented a certain new and useful Improvement in Carbureters, of whichthe following is a specification.

My invention relates to carbureters for the generation of gas for heat,light and power, and is well adapted for use on automobiles propelled byinternal combustion motors. l

A special object of my invention is the provision of an improvedcarbureter adaptedmore particularly for use on automobiles driven byinternal combustion motors, and the provision of certain details andfeatures of improvement tending to increase the general eliiciency andserviceability of a carbureter of this particular character. f

To the foregoing and other useful ends, my invention consists in mattershereinafter set forth and claimed.

In the accompanying drawings, Figure 1 is a vertical section, on anenlarged scale, of my improved carbureter, showing certain connectionsand parts 1n side elevation. Fig. 2 is an enlarged detail of the valvecontrolling the supply of hydro-carbon to the carbureter. Fig. ,3 is ahorizontal section on line 3 3 in Fig. 1. Fig. 4 is a horizontal sectionon line 4 4 in Fig. 1. Fig. 5 is a horizontal section on line 5 5 inFig. 1. Fig. 6 is a horizontal section on line 6-6 in Fig. 1.

Referring more particularly to Figs. 1 to 6 inclusive, my improvedcarburet-er J comprises a tank or receptacle 7' adapted tohold asuitable quantity of oil or hydro-carbon j. The said tank or receptaclehas a cover j, and this cover and the tank or receptacle are separatedby a centrally apertured dia phragm ja. A plate or disk j* 1s hung fromthe central portlon of the said diaphragm at a point below the centralaperture thereof, and connected with the said aperture by means of' acylinder of wire auze j, or other suitable reticulated materlal. Alittle farther down, the slightly conical diaphragm j is connected withthe lower side of the disk j* by another cylinder or rin of wire gauzeor other reticulated materia jf. It will be seen that this diaphragm jhas a central opening leading up into the interior of the gauze orreticulated cylinder j?. An

oil inlet pipe j@ leads to the bottom of the rereceptacle and suppliesthe interior thereof with suitable quantities of oil or hydrocarbon. Itis evident that the pi e js can extend downwardly on the outsi eifdesired, and discharge into the bottom of the receptacle, or throughthe side near the bottom, so long as the oil is introduced into the tankat or near the bottom thereof. Just above the nozzle or outlet portionofthis pipe js, there are provided a couple of diaphragms j and jmarranged one above the other, and the upper diaphragm j being providedwith perforat-ions ju. The peripheral portions of these two diaphragmeare rigidly separated by a ring j having peripheral' ring openings 7'13.The lower diaphragm j is preferably imperforate. In addition, the upperdiaphragm j is provided'with a centrally arranged aperture to which issuitably connected an air inlet pipe j, the latter leading to the sideof the receptacle and ultimately connectin with the air supply orressure pipes jl. round its outer. edge, t e diaphragm j is providedwith small openings j. At its top, the said carbureter is provided withva gas oflt'ake or pipe j". With this arrangement, the air entering therecept-acle through the pipe j flows into the chamber provided betweenthe diaphragms j and jl". Theair then escapes through the apertures orperforations j and j, where it then mingles with the body of oil orhydro-carbon j. -The gas thus formed then passes upwardly throughv thecentral opening in the diaphragm j, where it then passes upwardly throuh the screen or-reticulated cylinder j". A er this, the gas passesthrough the sides of the screen or reticulated cylinder j, and thenupwardly through the central opening in the diaphragm ja. From thispointthe gas escapes through the pipe or oftake jl". vIn this way, a superiorform of gas is manufactured in said carbureter from air which isadmitted 'directl to the hydro-carbon. -After this,

as. exp ained, the' gas is forced to pass' upw'ardlylthrough successivescreening or v more orlessiinely reticulated means before lit is allowedto escape for use. The supplyA fof oil to the carbureter is controlledby a needle valve j connected inthe oilsupply pipe j, Itwill be seenthatthis valve 1s operated by a spring-held pistonjz", e

. bureter, the greater the supply of air thereto, and vice versa. In.this way, the said `C arbureter can' be run on easy'pressure, or can becrowded to its Afull capacity, without requiring anyl manual adjustmentof any of its parts or controlling devices. The air passing throughthebody of oil impoverishes it to-a considerable extent, but the newsupply of oil being furnished to the chamber below, the air openingimmediately enriches the upper portion of the oil body, so

that the gas produced is of a substantially uniform quality. The oilsupply tank (not shown) is arranged in any suitable position and isconnected by apipe with theoil supply pipe 7'19 leading to thecarbureter.

With further respect to the carbureter, it will be seen that theapertures j permit any oil of'condensation occurring above the diaphragm7'6 to ow back to the receptacle containing the main body of oil orhydrocarbon. A particular object of the carbureter .I is to preserve atall times the correctproportion of air and oil.- The air pressure isbound to vary somewhat, re# gardless of the particular. use of saidcarbureter, and with the automatic valve. the correct proportion willalways be retained. In other words, there is a certain proportion whichgives the most combustible mixture which can be produced, and theautomatic valve preserves this proportion at all times. Furthermore, inthe carbureter fresh oil is constantly supplied at a point below, sothat it rises and keeps full, rich oil at the top of the body of oil inthegenerator. Inthis way, the air is not permitted to impoverish theoil, so to speak, the oil through which air passes always being of thesame gas-making value or quality.

One of the important features of the general construction consists inincreasing the power of the engine without increasing the :cooling theengine. vThe speed. This is done cylinder of the engine.

For example, this can be done by closing off the surplus air from thepump,-that is, the air which is Iordinarily escaping into theatmosphereand which is not used for ump Supplies certain amount of air, an acertain portion of this air is used in cooling the engine,

and what is left can be used for any other vpurpose whatever. As stated,this surplus air can .be thrown. into the carbureter, so as to increasethe pressure at this point and thus supply the gas under pressure to theengine. Of course, the gas supplied to the engine is always underpressure, but the important thing is to increase the pressure in orderto increase the power of the engine without increasing its speed.Ordinarily, and' at all times, theair supplied from the pump goes partlyto the engine to cool the same, and partly to the carbureter, and overand above this quantitythere is a surplus which is going anywhere,wherever .it is needed, or to the atmosphere if there is no way in whichit can be used.

It is obvious that my improved carbureter can be used forvariouspurposes and in variousconnections wherever gas is required either forlighting, heating or the development of power. For this reason, I do notlimit myself to the exact details shown and described. d

What I claim as my invention is:

In a carbureter, the combination of a receptacle for holdingthehydrocarbon, a couple of thin horizontal walls arranged one above theother and with a slight space between, means for rigidly connectingtogether the horizontal portions of said upper and lower walls, therebeing air outlets arranged at intervals around the periphery of thestructure thus formed by the connectedupper and lower walls, means forsupplying air to the chamber between the said upper and lower walls, thestructure thus formed being submerged in the body of hydro-carbon, andan oil inlet arranged immediately below the central portion of said airsupplying structure.
